The present disclosure relates to a system for treating biological samples comprising a conveyor system configured to convey container holders intended to support containers containing biological samples, such as biological liquid samples.
In a known manner, such a conveyor system comprises:
Such a conveyor system considerably limits the tedious manipulations for an operator and ensures a high conveying capacity and a high analysis rate, in particular when a container holder has to be conveyed between different analysis and/or measurement devices.
In addition, in the event of failure of the self-propelled conveyor carriage, all it needs is to replace the latter by another self-propelled conveyor carriage, which ensures a short shutdown duration of the conveyor system, and therefore considerably limits the unavailability, for the analysis laboratory, of a biological analysis system equipped with such a conveyor system. It is also possible to equip the conveyor unit with two self-propelled conveyor carriages, such that one of the self-propelled conveyor carriages could ensure a permanent service when reloading the other self-propelled conveyor carriage or during maintenance thereof. Furthermore, the presence of two self-propelled conveyor carriages ensures an increased conveying rate.
Furthermore, since the conveyor carriage is self-propelled, the conveyor track may be essentially “passive”, and therefore be defined by a simple carriage guide element, such as a guide rail, which considerably simplifies the conveyor system and increases the reliability of such a system, by reducing costs and enables a more easily configurable, quicker and easier installation.
However, when a container holder is driven in translation by the self-propelled conveyor carriage, the frictions of the container holder on the holder guide element generates noise which may be a source of discomfort for the operators. In addition, these frictions increase the electrical consumption of the self-propelled conveyor carriage and therefore affect the autonomy of the battery of the self-propelled conveyor carriage.
Furthermore, when a container holder is transferred by the self-propelled conveyor carriage from the guide track to a receiving location (and therefore moved perpendicularly to the conveying direction of the self-propelled conveyor carriage), the container holder could tilt vertically, because of the frictions of the lower surface of the container holder on the holder guide element, which could induce a non-optimum positioning of the container holder in the receiving location and therefore affect gripping of the container holder by a loading mechanism associated with the receiving location.
The present disclosure aims to overcome these drawbacks.
Hence, the technical problem at the origin of the present disclosure consists in providing a system for treating biological samples comprising a conveyor system which has a simple, economical and reliable structure, while ensuring a high conveying capacity, an optimized analysis rate and a simple and quick maintainability.
To this end, the present disclosure relates to a biological sample treatment system, such as a biological analysis system, comprising:
Such a configuration of the conveyor system, and in particular of the self-propelled conveyor carriage, allows moving a container holder at a distance from the carriage guide element and therefore avoid any friction between the container holder and the carriage guide element during the displacements of the container holder along the travel path and also during the displacements of the container holder transversely to the travel path (for example when loading the container holder in a receiving location).
This results in a better autonomy of the battery of the self-propelled conveyor carriage and therefore of the electrical charging cycles of the battery which are more spaced over time. Thus, the shutdown periods of the self-propelled conveyor carriage are considerably reduced.
Furthermore, the absence of friction between a container holder and the carriage guide element during the displacements of said container holder along the travel path substantially reduces the noise generated by the conveyor system, and considerably improves the comfort of an operator.
In addition, the absence of friction between a container holder and the carriage guide element during the displacements of said container holder transversely to the travel path (in particular when loading the container holder in a receiving location) ensures an optimum positioning of said container holder in a receiving location, and consequently an optimum gripping of said container holder by a loading mechanism associated with the receiving location.
Thus, the conveyor system of the biological sample treatment system according to the present disclosure has an increased reliability compared to the conveyor systems of the prior art, while ensuring a further improved conveying capacity and analysis rate.

The biological analysis system 1 according to the present disclosure is intended to fluidize the treatment flows of the samples in an analysis laboratory, in order to increase productivity and quality thereof (reduction of labor and errors). Thus, it goes without saying that the conveyor system 2 according to the present disclosure is configured to communicate with the control unit 41, which manages the workloads of the different analysis and/or measurement devices 5 (such as the tests to be performed per sample), and transmits them to the conveyor system 2 and to the analysis and/or measurement devices 5 such that the different containers 16 are conveyed towards the analysis and/or measurement devices 5 according to the test requests and the capacities of each analysis and/or measurement device 5.

For example, the analytical portions may include one or more station(s) among a biochemistry (for example photometry) station, an immunochemistry (for example immunofluorescence) station, a coagulation station, a hematology station and a cytometry station.
For example, the post-analytical portions may include a short-term storage station and/or a long-term refrigerated storage station.
